The "benefit" I can see is that the domU disk image with partitions and
LVM remains compatible with Kickstart.  But there are other ways to
bootstrap a Red Hat or CentOS image.

I'm seeing us move rapidly towards a model in which all our hosts are
virtualized, but the Linux distribution we use remains encumbered by
features designed for bare iron deployments.  I hope a new OS will
emerge some day--one optimized for virtualization.  Eliminate the
old-fashioned boot loader, disk partitions, block schedulers, RAID
options, etc.  Move simple network services into dom0, or maybe stubdom.

Basic Red Hat installs now require 1GB+ disk and 256MB RAM to be usable.
That's because the OS bundles every package it will need to run
standalone on bare iron.  I realize disk/memory are now a cheap
commodity but the bloat reminds me of some of the reasons I left behind
a certain proprietary OS.
